2. Measurement Principle
Goniophotometer with Moving Mirror (also called Goniphotometer with Rotating
Mirror) can test luminaries rotating in the prescribed burning position and around
the vertical axle and a reflecting mirror rotates around the horizontal axle,
meanwhile, a synchronous axle will rotate toward the opposite direction
synchronously. The photometer head located at a fixed position of the limiting
photometric distance in front of the reflecting mirror to gather the light in each
direction.
The rotation priority is determined by the software. If mirror axle is took precedence
of rotation, the goniophotometer will continuously measure the luminous intensity
at each γ angle on a vertical plane determined by the C angle, the measuring trace
is equivalent to the longitude. Similarly, while the luminaries axle is priority, the
system will continuously measure the luminous intensity at each C angle on a
conical surface determined by the γ angle, the trace can be looked upon the woof.
See the following figure.

LSG-2000 Goniophotometer with Moving Mirror
The LSG-2000 fully meet LM-79 Clause 9.3.1, CIE and GB standards for
Goniophotometric of luminaries, this system is used to measure spatial luminous
intensity distribution of luminaries for floodlight, street lighting and interior lighting,
and other photometric parameters such as spatial iso-intensity curve, intensity
distribution curve of each section (shown in rectangular coordinate system or polar
coordinate system), iso-illuminance distribution curve, luminance limitation curve,
luminaries efficiency, glare grade, effective beam angles, upward luminous flux ratio,
downward luminous flux ratio, total luminous flux, effective luminous flux,
utilization factor and electric parameters (wattage, power factor, voltage and
current) of luminaries etc.
LSG-2000 Can test all of the above luminaires
4. Specifications

5. Laboratory Requirements
1) Room Requirements according to CIE
Model Dark Room (W*H*L) Operation Room(W*L)
LSG-2000B 5*6*8~30m 4*4m
LSG-2000 4*5*8~30m 4*4m
LSG-2000S 4*4.2*8~30m 4*4m
The dark room wall, ceiling and floor should be all coated with dull black paint or
be covered by black cloth and black carpet.
Air-conditioner: be set in the dark room to control the temperature around
lamps to the standard value upon the CIE requirements.
Note: LISUN GROUP engineer dept will submit the Lab Design support documents
according to the customer’s real lab size after the formal purchase order was
confirmed

2) Requirements of Eliminating the stray Light
Luminaires must be where the photodetector can only receive the light
reflected by the rotating mirror in the LSG-2000 system. The light given off
directly by the luminaries and reflected by the wall and floor is warded off
by the light fence. Internal surface of the dark room and dark path together
with the surface of the light fence should be painted unpolished black or be
covered by black cloth and black carpet.
3) Temperature of the Environment
Temperature around the lamp or luminaries must be 25℃±1℃ during the test.
Exceptions can be given according to relative lamps as following.
a. Tungsten Incandescent Lamp: 25℃±5℃
b. Double-caps Fluorescent Lamp: 25℃±1℃
c. High Pressure Mercury Lamp: 25℃±2℃
d. Metal Halogen Lamp: 25℃±2℃
e. High Pressure Sodium Lamp: 25℃±2℃
f. Low Pressure Sodium Lamp: 25℃±2
4) Airflow
Airflow may be induced by natural aeration, air conditioner or movement of the
luminaries in the goniophotometer, but the speed of the airflow couldn’t
exceed 0.2m/s.
5) Vibration and shock
When the lamp is in lighting, the vibration couldn’t exceed 10m/s2(4 ~
3000Hz), or the moving scope of the lamp couldn’t exceed 30mm (at most
4Hz)
6) Smoke, Dust and Moisture
The test environment must free from smoke, dust or moisture. At the same
time, even not during the measurement, smoke, dust or moisture will also
influence the reflectance of the reflecting mirror and induce more stray light.
So, the test room must be kept clean, no smoke and dry. The humidity should
be less than 60% RH.
6. Service
1) Installation and Training
LISUN GROUP engineers will take responsibility for installation and Training of
the system at the customer’s
2) Period of Guarantee: 24 months
